I think you're going to get much better feedback if you let people actually use your service. How much trouble could it be to make a bunch of HN invitation codes? You're essentially asking us to critique your front page and screencast.

That said, from the screencast itself, this seems like a tremendous amount of work for not a lot of benefit--especially if I have to (and that's what it seems like) go back into your reader to change these scores and then return to GReader. Why shouldn't I just hit "j" in GReader when I come up to something I don't like as opposed to doing all your work?

Also, the screencast itself: (this is basically just pedantry) you should normalize the vocals. The levels jump around. And while I'm glad you took the time to run it through what sounds like a noise-reduction filter, it would sound much better if you were talking louder and clearer when you recorded it.
